AbstractFor pre-research on ice cloud detection equipment, the design and test of a low conversion loss (CL) 4th-harmonic mixer working at the central frequency of 670 GHz based on an anti-parallel Schottky diode are presented. In order to improve the mixing efficiency, a two-stage local-oscillator (LO) compact-microstrip-resonate- cell (CMRC) low-pass-filter (LPF) is utilized to suppress the second mixing item (f= vertical bar 2*f(LO )- f(RF)vertical bar), the third harmonic of LO signal (f = 3*f(LO)), and RF signal. The LO frequency is only one-quarter of the RF frequency which significantly reduces the complexity and cost of the LO chain. The measurement result shows that the Single-Side-Band (SSB) conversion loss is between 16. 7 dB to 22. 1 dB from 640 GHz to 700 GHz at room temperature. The minimum conversion loss is 16. 8 dB at the RF frequency of 665 GHz.
